TG, triglyceride

Different lowercase letters in the same array indicate a significant difference between treatments (P<0.05). After 24 h in serum-free medium, hepatocytes were incubated for 48 h either with no addition as a control or with 50 nmoll–1 insulin, 100 nmoll–1 insulin, 150 nmoll–1 insulin, 200 nmoll–1 insulin, 5 mmoll–1 glucose, 30 mmoll–1 glucose, 50 nmoll–1 insulin + 5 mmoll–1 glucose or 50 nmoll–1 insulin + 30 mmoll–1 glucose added. The standard culture medium contained 25 mmoll–1 glucose before additions
